ELEVATOR.

Specification of Letters Patent.

Patented Feb. 27,1912.

Application filed August 11, 1910. Serial No. 576,657.

To all whom t may concern:

Be it known that I, FREDERICK Gr. Roular- Lnn, a citizen of the United States, residing at 2137 Hastings street, Chicago, in the countyv of'Cook and State of Illinois, have invented a new and useful Improvement in Elevators, of which the following is a specification.

My invention relates particularly to means for locking the controlling-mechanism of an elevator against actuation when the elevator-door is thrown open, and maintaining the controlling-mechanism in such condition until the door is fully closed, thus preventing careless starting of the elevator and obviating the danger attendant thereon.

My primary object is to provide improved and simplified mechanism which can be manufactured `and installed at moderate eX- pense, and which is operative to accomplish the purpose indicated.

The invention is illustrated in yits preferred embodiment in the accompanying drawings, in whichlFigure 1 represents a broken plan sectional view of an elevator-shaft and elevatorcage equipped with my improvements; Fig. 2, a broken vertical section taken as indicated at line 2 of Fig. 1 and illustrating the cage-carried portion of my device; Fig. 3, a broken vertical section'taken as indicated at line 3 of Fig. 1; Fig. 4, a broken vertical section taken as indicated at line 4 of Fig. 1; Fig. 5, a broken perspective view showing a portion of an elevatorshaft, the elevator-door and the portion of my device attached thereto; Fig. 6, a broken bottom view of the cage with my mechanism applied, the view showing also the dooractuated member which actuates the locking device carried by the elevator-cage; and Fig. 7 a broken vertical section showing a different form of elevator-controlling mechanism (electric-controller) and the manner in which the same may be connected with the locking-mechanism which I employ.

In the preferred construction, A represents an elevator-shaft provided with doors A (one shown); and B, an elevator-cage suspended in the shaft in the usual manner (not shown), and equipped with controlling-mechanism B of the usual construction.

The elevator-shaft A may be of any usual construction. At each floor is abeam, or sill,

1 to which is attached a vertically-disposed door-actuated rock-member 2. The rocklnember 2 is connected by vertical hinges 3 to a vertically-disposed bar 4 which is secured in any suitable manner to the vertical surface of the sill 1, the rock-member 2 and supporting-member 4 being thus disposed within the elevator-shaft, preferably immediately below the rear portion of the door in the closed position thereof, but slightly back of the plane of the door. Said rock-member 2 has a laterally-projecting arm 5 adapted to be engaged by a cammember 6 when the door is thrown open. The arm 5 is equipped at its extremity with an upwardly-projecting stud 7 which is adapted to be engaged by a hooked-projection 8 attached to the rear lower corner of the door, the member 8 being located slightly in the rear of the rear end of the member 6 and somewhat above the member 6. The member 6 extends horizontally across the bottom portion of the door and has a beveled surface 9 at its rear end which is adapted to engage the arm 5 when the door is thrown open, thereby to swing the member 2 away from the wall of the elevatorshaft and cause it to actuate the controllerlocking mechanism carried by the cage. The member 2 is elongated vertically, so that it will serve its function, even though the car does not stop exactly at the landing, preparatory to opening the door to the elevator-shaft. The cam-member 6 may comprise a channel-bar whoseV flanges abut against the lower member of the door-frame and whose web 10 is thus disposed at some distance from the door. The flanges of the member 6 are cut awayat their rear ends adjacent to the web, and the projecting portion of the web is bent to an oblique position, as shown in Fig. 5, thereby to provide the beveled surface 9.

The rock-member 2 coacts with the controller-locking mechanism C carried by the elevator-cage and disposed beneath the floor thereof. The mechanism C comprises a mounting, or plate, 11 which is securely fastened to the floor of the elevator-cage at the lower side thereof; a slide-bar 12 movable in guides 13 depending from the lower side of the plate 11, saidbar 12 being connected by links 14 with the lever l5 of the controllingmechanism; a locking-bolt 16 for the bar 12 which is pivotally connected with the free end of the lever 17 whose opposite end is joined by the pivot 18 to `t-he supportingplate 11; and an .actuating-member 19 for the lever 17, said member 19 comprising a bar, or plunger, having one end connected `by a pivot 20 to the intermediate portion of the lever 17 and having its opposite end movable through the guide 21 carried by the edge-portion of the plate 11 which is disposed adjacent the wall of the elevatorshaft, the extremity of t-he member 19 being thus in position to be engaged by the rockmember 2 when the latter is turned to project into the elevator-shaft in t-he manner shown in Fig. 6. The spring 22 acts upon the lever 17 and serves normally to project the-bar 19 through the guide-member 21, so that the extremity of the member 19 will be adjacent the rock-member 2 when the oo-r of the cage is at or near the level of the landing, as shown in Fig. 4l.

The locking-bolt 16 is adapted to enter a slot, or locking-notch, 23 with which the bar 12 is provided, when the lever 15 is in the neutral position. The locking-bolt 16 is movable through a guide 24 with which the plate 11 is equipped on its under side, and the extremity of the locking-bolt is tapered somewhat, as shown in Fig. 6, to insure the bolt entering the socket in the bar 12, even though the lever 15 should not be exactly at the intermediate position when the door of the elevator-shaft is thrown open, thereby actuating the locking-mechanism C.

The controlling-mechanism B which controls the actuation of the elevator-cage is of the well kno'wn form in which a rockshaft 25 with which the starting and stopping lever 15 is connected, serves to control 4the hydraulic means for operating the elevator.

In Fig. 7, B2 represents the controllinglever of an elevator operated by electric power. In this case, the controller-lever is equipped with arms 26 connected by rods 27 with a lever 28 which is supported on a pivot 29 carried by a bracket 30 depending beneath the elevator-cage. The lever 2S is equipped with an arm 31 which is connected with the links 14 of my improved mechanism. The mechanisml is in other respects similar to the mechanism already described.

The manner of operation will be readily understood. When the elevator arrives at a landing, the actuating-bar 19 of the cagecarrying locking-mechanism C is brought into the relation with respect to the rockmember of the elevator-shaft equipment which is illustrated in Figs. 1 and 4; and when the door A of the elevator- Ashaft is thrown open, the cam 6 engages the-door is open or partially open. I/Vhen action the nger or projection 8 engages the stud 7 of the rock-member 2 and swings the bar 2 to its normally closed or inoperative position parallel with the adjacent wall of the elevator-shaft. t

The foregoing detailed, description has been given for clearness of understandingv only, and no undue limitation should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.
